I DISPLACEMENT ELEMENT FOR LIQUID CONTAINERS.

Application filed November 10, 1919.. Serial No. 337,004.

To all whom it may concern:

Be it known that I, LINNAEUS E. BAKER, a citizen of the United States. residing'at Fort \VayneQ in the county of Allen and State of Indiana, have invented new and useful Improvements in Displacement Elements for Liquid Containers, of which the following'is a specification.

My invention relates-to displacement elements for liquid measuring vessels. and are designed to make possible accurate measure ment therein by the use of a standard linear scale. 4

Heretotore' it has been necessary to ensure exact measurement in containers having a standard scaleto malre such containers with uniformly accurate side walls, which is impractical at least in the cheaper vessels. To ensure accurate measurement the graduations have been put upon each vessel separately by calibration.

. My invention consists in inserting in a ressel having a standard linear scale and a minimum diameter greater than is required for said scale. one or more displacement elements to reduce the cross sectional liouid area of said vessel so that all quantities meas ured therein will accord with the quantites indicated on the scale.

By the use of my invention standard meas uring vessels that must be passed by sealers of measures from time to time, may be corrected as to their various cross-sectional areas by such public otlicers quickly and cheaply wherever installed for use.

In the particular embodiment of my invention selected for illustration; the vessel to contain and measure the liquid is the elevated container of a so-called visible dis pensing apparatus for gasoline.

Figure 1, is an elevation of the container with par-ts broken away to show the displacement elements in position therein,

Fig. 2'. is a cross-section on the line 22 of Figure 1, 1

Fig. 3, detail, is a perspective of awedge shaped displacement element to correct a conical shaped container whose lower end is largest,

a, a detail, is a perspective of a wedge shaped displacement element to correct a conical shaped contanier whose upper end is rest, and

1 tail, is perspective as a diselemen or gxnaily of uniform rectangular cross-section, but cut to equalize the cross-sectional liquid area at all points on the scale.

(* hereinafter tobe described. The top 0 is secured to the bottom 0, by tie rods 0,

and the joints are made leak tight with litharge or in any other suitable manner.

The container C, here shown is made of metal with windows 0 of glass or other transparentv material, and at a convenient point on or near this window is a standard linear scale 0*, graduated to gallons and half gallons from 0 to 10 to indicate the quantity of gasoline discharged from the container.

On the top 0 at a convenient point on its side is a horizontal nonremovable threaded stud (.7, provided with a nut d and a hole (Z through which may be passed the wire (Z of a standard seal (i to prevent the unauthorized addition, removal or exchange of displacement elements D, D D suspended through holes (Z from the stud The, displacement elements are held in alignment by the recess 0 formedin the bottom 0. The displacement elements are .of any suitable materialand 01'' any shape necessary alone or in combination to make the liquid cross sectional area of the container the same at all points on the scale and to conform to the standard of the scale. For instance, if the container C, is not'a cylinder or other form having a uniform crosssectional area, or is not conical, a displacement element D similar to that shown in Figure .5 maybe used to equalize all cross sectional areas, and then one or more plain elements of uniform rectangular cross-section like D, D D may be added to make the several equal cross-sectional areas of the container conform to the standard of the scale. If the container C, is conical, or it its cross-sectional area from graduation to grad nation conforms to that of a conical container, then a wed e shaped displacement element B like those shown in Figs. 3 and e;- ma

or at bottom; the latter M are top, to equalize all crossand then one or more elera ed, the former if the may be held in place in the container in tional areas of the container conform to the standard of the scale.

When so corrected'by the displacement elements, if the surface of the liquid in the container C, stood at 5 on the scale and five more gallons of liquid were placed in the container the surface of the liquid would stand at 0, on the scale. Then if three gallons'were Withdrawn from the container, the surface of. the liquid would stand at 3 on the scale, etc. l

by substituting for the several displacement strips necessary to make the correction, a single displacement element having the same crossseotionah characteristics as the several combined strips.

The shape of the displacement elements is immaterial so long as the various. desired cross-sectional areas are obtained. I

The displacement element or elementsused any convenient manner.

I claim as my invention and desire to secure by Letters Patent of the United States:

1. In combination with a dispensing measuring vessel having different cross sectional areas and having a standard scale to indicate the quantity of liquid therein'tdisplaeement means secured within the vessel and so shaped as. to make the cross sectional areas thereof uniform and'correct the reading on thescale. v

2. In combination with a dispensing-measluring" vessel of uniform cross, sectional area -and having astandard scale to indicate the Obviously the same result be attained quantity of liquid therein; one or more displacement strips secured within the vessel,

said strips shaped'to make the cross sectional area thereof uniforxn'an'd conformable tothe reading on the scale.-

In testimony whereof I have hereunto set my hand in presence of two subscribing I witnesses Linnaeus E. BAKER.
